 By default, Eclipse doesn't automatically save your files when you build.  If you would prefer that behavior, go to Window > Preferences > General > Workspace.  Set the "Save automatically before build" checkbox.  This avoids build errors if you forget to save a file that you've changed. By default, Eclipse doesn't automatically save your files when you build.  If you would prefer that behavior, go to Window > Preferences > General > Workspace.  Set the "Save automatically before build" checkbox.  This avoids build errors if you forget to save a file that you've changed.

 +===== Unlimited Console Buffer =====
 +By default, Eclipse limits debug console output to 80,000 bytes.  Rosegarden generates a lot of debug output.  It's a good idea to turn this limit off.  Go to Window > Preferences > Run/Debug > Console.  Uncheck "Limit console output".
